Cheese Safety Tips for Pregnant Women
Pregnancy increases vulnerability to foodborne illness, particularly from Listeria monocytogenes, a bacterium that can cross the placental barrier and cause miscarriage or stillbirth. Certain cheeses—especially soft, unpasteurized varieties—pose higher risk. Learning proper cheese selection, storage, and handling protects both you and your developing baby.
Choose Safe Cheese Types & Verify Pasteurization
The FDA and CDC recommend pregnant women avoid soft cheeses (brie, feta, queso fresco, camembert, roquefort) unless labeled as made from pasteurized milk. Hard cheeses like cheddar, parmesan, and Swiss are safer due to lower moisture content, which inhibits Listeria growth. Always check the label for "pasteurized milk"—unpasteurized cheese carries significantly higher contamination risk. When dining out, ask servers whether soft cheeses are pasteurized; never assume. Blue-veined cheeses are particularly risky and should be avoided unless confirmed pasteurized by the manufacturer.
Proper Storage Temperatures & Cross-Contamination Prevention
Store cheese at 40°F (4°C) or below to prevent Listeria multiplication; check your refrigerator temperature with a food thermometer weekly. Keep cheese in sealed, airtight containers on a dedicated shelf away from raw meats, poultry, and seafood to prevent cross-contamination. Use separate cutting boards for cheese and raw proteins—never reuse boards without hot soapy water washing. Wash hands with soap and warm water for 20 seconds after handling any raw food item before touching cheese. Discard any cheese that has developed mold, off-odors, or surface sliminess, even on hard varieties.
Cooking Methods & Common Mistakes to Avoid
If you're heating cheese in dishes, ensure it reaches an internal temperature of 165°F (74°C) for full safety—use a food thermometer to verify. Many pregnant women mistakenly believe pasteurized soft cheese is completely safe at room temperature; it still requires refrigeration and has a shorter shelf life than hard cheese. Never eat pre-sliced cheese that's been left unrefrigerated for more than 2 hours (1 hour if above 90°F). Avoid unpasteurized cheese spreads, dips, and prepared cheese sauces from unknown sources. When in doubt, contact your OB-GYN or consult the FDA's pregnancy food safety guidelines for specific products.
